' WIRE FENCING.

SPECIFICATION forming part of Letters Patent No. 514,672, dated February13, 1894. Application filed April 1'7, 1893. Serial No. 470.735- (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN D. CURTIS, a citizen of the United States,residing at VVorcester, in the county of Worcester and Commonwealth ofMassachusetts, have invented certain new and useful Improvements in WireFencing, of which the following is a specification.

My invention relates to that style of wire fencing described in myapplication for a patent upon a machine for making wire fencing, filedDecember 29, 1892, Serial No. 456,616.

The object of my invention is to produce awirefencing light in weight,economical to manufacture, and attractive in appearance. This Iaccomplish by using strands non-circular in cross-section, andpreferably, each with one fiat side, between which a barb with a flat,bearing surface for a part of its length may be secured in place by thetwisting of the main strands of the fencing.

In the drawings, Figure 1 is a side View of my improved fencing withoutbarbs, showing the two strands 2, 3 twisted together to form thecompleted cable 1. Fig. 2 is a side view of my improved fencing withbarbs, showing two barbs 4, 5, the barb 5 on the left indicating indotted lines the relative positions of the'ends of the barb, and theplane of the feed of the barb wire. Fig. 3 is an end view looking in thedirection of the arrow, Fig. 2. Fig. t shows a sectional view of threeforms in which the main strands may be conveniently made, and alsoillustrates the manner in which the barb is held in place. Fig. 5 showsa barb severed from the main barb wire, in the form in which it isinserted between the strands of the fencing.

In manufacturing my improved fencing, the barb is inserted between themain strands of the fencing, which are then twisted to gethersufficiently to hold the barb in place. The details of the process arefully described in my application above referred to. My barb ispreferably fiat at the point where it is held between the two strandsforming the cable. I do not confine myself to strands of any particularshape in cross-section, it only being necessary that the strands shallbe of such shape that, when twisted together, they shall hold the barbin place between their contact surfaces. I have shown four such forms inthe drawings. In practice, I prefer to use strands half-round orsegmental in cross-section, as shown in Fig. 3. I also prefer to. bendthe barb'points at an angle with the contact surfaces of the strands, asthe barb is thus held in place more securely.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. In combination with a two-strand, twisted wire cable for fencing,composed of strands non-circular in cross-section, with two surfacesadapted to make a joint when twisted together, a metal barb held inplace between the surfaces of the main strands of the fencing by thetwist of said strands, the ends of the barb being bent at an angle withthe contact surfaces of the two main strands of the fencing,substantially as shown and described.

2. In combination with a two-strand twisted wire cable for fencing,composed of strands non-circular in cross-section, with two surfaces,adapted to make a joint when twisted together, a metal barb heldin'place between the surfaces of the main strands of the fencing by thetwist of said strands, the ends of the barb being bent substantially atright angles to the contact surfaces of the two strands of the fencing,substantially as shown and described.
